Adafruit Teensy 3.5 without headers

The Teensy 3.5 is a compact development board offering an impressive blend of power and versatility. With a 120 MHz ARM Cortex-M4 processor featuring a floating-point unit, it’s perfect for those requiring robust performance in a small package.

Specifications include a 512K Flash, 256K RAM, and a 4K EEPROM, as well as an array of I/O options: 62 pins (42 breadboard-friendly), 25 analog inputs, 2 analog outputs, and 20 PWM outputs. All digital pins are 5V tolerant, enhancing its compatibility with various peripherals.

An ideal choice for projects needing efficient data transfer, this board boasts six serial ports, three SPI ports, and three I2C ports. It is equipped with a USB Full Speed port, a native micro SD card port, and an Ethernet MAC capable of 100 Mbit/sec.

The Teensy 3.5 also features a variety of advanced capabilities like an I2S audio port for digital audio projects, a cryptographic acceleration unit for secure applications, and hardware timers for accurate time-keeping. Its random number generator and CRC computation unit ensure reliability in your designs.

Although the Teensy 3.5 harnesses the familiar Arduino IDE (Teensyduino) for easy programming, it offers enhanced functionality with C language programming options.
